A construction worker with a weight of 850 N stands on a roof that is sloped at 20. What is the magnitude of the normal force of the roof on the worker?

The roof is on the 20 degrees slope with the surface. We need to find the magnitude of normal force of the roof on the worker. It can be calculated as :

[tex]F_N=mg\ cos\theta[/tex]

[tex]F_N=850\times \ cos20[/tex]

[tex]F_N=798.73\ N[/tex]

So, the normal force of the roof on the worker is 798.73 N. Hence, this is the required solution.

The magnitude of the normal force of the roof worker is 798.66 N

The parameters given in the question are

Weight= 850 N

angle= 20°

The formula for calculating the magnitude of the normal force of the roof worker is

= mg cos 20°

= 850 × 0.9396

= 798.66

Hence the magnitude of the normal force of the roof worker is 798.66 N
